A pet shop wants to give a discount to its clients if they buy one or more pets and at least five other items. The discount is equal to 20 percent of the cost of the other items, but not the pets.

Use a class Item to describe an item, with any needed methods and a constructor

public Item(double price, boolean isPet, int quantity)

An invoice holds a collection of Item objects; use an array or array list to store them. In the Invoice class, implement methods

public void add(Item anItem)

public double getDiscount()

Write a program that prompts a cashier to enter each price and quantity, and then a Y for a pet or N for another item. Use a price of –1 as a sentinel (i.e. -1 means all values have been entered). In the loop, call the addmethod; after the loop, call the getDiscount method and display the returned value.

Create an interface named Shippable with a method named getVolume and another named getWeight. Neither has parameters and both return a number

Write a program that "cuts" a deck of 52 playing cards. Given a cut position, the process of cutting the deck refers to taking all cards before the cut position and moving them to the end of the deck. The order of the cards is maintained. For example, if the deck is cut at position 25, the first 25 cards of the deck are moved to become the last 25 cards of the deck. The new first card in the deck is card 26, and the new last card of the deck is card 25.

The deck of cards is represented as a 52-element integer array, with values 1 through 52 representing the different cards. The initial population of the deck is done for you.

Your program should accept a single integer input, which is the cut position. If the input is less than 1 or greater than 52, your program should print "ERROR" and exit. Otherwise, after performing the cut, your program should print out the new deck, with one card value on each line.

Use Java

Sample values from an experiment often need to be smoothed out. One simple approach is to replace each value in an array with the average of the value and its two neighboring values (or one neighboring value if it is at either end of the array). Given a class Data with instance fields

private double[] values;

private double valuesSize;

implement a method

public void smooth()

that carries out this operation. You should not create another array in your solution.

I can not get the summary report to show in the output it just keeps running after i enter the names, scores, and then / /. Can someone help me I am using codeblocks but I might be able to figure out even if you use another IDE>

This is my code

#include <iostream>

using namespace std;

int main()
{
string name;
double score =0;
int totalStudents = 0;
int A=0,B=0,C=0,D=0,F=0;
cout << "Enter student name" << endl;
cin >> name;

while (name!="//"){
cout << "Enter student score" << endl;
cin >> score;
if(score>=90){
A++;
cout<<name<<" "<<score<<" A"<<endl;
}
else if(score>=80&&score<90){
B++;
cout<<name<<" "<<score<<" B"<<endl;
}
else if(score>=70&&score<80){
C++;
cout<<name<<" "<<score<<" C"<<endl;
}
else if(score>=60&&score<70){
D++;
cout<<name<<" "<<score<<" D"<<endl;
}
else if (score>=0&&score<60) {
F++;
cout<<name<<" "<<score<<" F"<<endl;
}
cout << "Enter student name" << endl;
cin >> name;
totalStudents++;
}
cout << "Enter student name" << endl;
cin >> name;
cout << "Summary Report" << endl;
cout << "Total Students count " << totalStudents << endl;
cout << "A student count " << A << endl;
cout << "B student count " << B << endl;
cout << "C student count " << C << endl;
cout << "D student " << D << endl;
cout << "F students " << F << endl;
return 0;

Description

Write a program that computes the letter grades of students in a class from knowing their scores in a test. A student test score varies from 0 to 100. For a student, the program first asks the student’s name and the student’s test score. Then, it displays the student name, the test score and the letter grade. It repeats this process for each student. The user indicates the end of student data by entering two consecutive forward slashes ( // ) when asked for the student name. At the end, the program displays a summary report including the following:

·       The total number of students.

·       The total number of students receiving grade “A”.

·       The total number of students receiving grade “B”.

·       The total number of students receiving grade “C”.

·       The total number of students receiving grade “D”.

·       The total number of students receiving grade “F”.

The program calculates a student's the letter grade from the student's test score as follows:

A is 90 to 100 points

B is 80 to 89 points

C is 70 to 79 points

D is 60 to 69 points

F is 0 to 59 points.

Requirements

Do this exercise using a While statement and an If/Else If statement.

Write a program that "cuts" a deck of 52 playing cards. Given a cut position, the process of cutting the deck refers to taking all cards before the cut position and moving them to the end of the deck. The order of the cards is maintained. For example, if the deck is cut at position 25, the first 25 cards of the deck are moved to become the last 25 cards of the deck. The new first card in the deck is card 26, and the new last card of the deck is card 25.

The deck of cards is represented as a 52-element integer array, with values 1 through 52 representing the different cards. The initial population of the deck is done for you.

Your program should accept a single integer input, which is the cut position. If the input is less than 1 or greater than 52, your program should print "ERROR" and exit. Otherwise, after performing the cut, your program should print out the new deck, with one card value on each line.

Using the provided m1_mbox.txt, write a program that reads the data from the file, locates the lines containing sender information (those lines begin with 'From:'), and extracts just the email address of the sender of each message. It should then duplicate the set of email addresses for senders, and write the duplicated list to a file called senders.txt, so that each sender appears in the output file only once. In addition, your program should print to the screen the following stats: total number of email messages in the file, and number of unique senders. Your program should expect the input and output files to be in the same directory and you should hardcode this into your program (that is, do not use command line arguments).

State the data cube computation methods. Give example for each method
